cansl ,have beenV madeof sheet-metal vand have been heavy and diicult'to empty, It is an portant objectief 'my presentinvention to provide a pivotal mountingiora bobbin receiver yso constructed that it can be swung forwardly to aposition inwhich'the rbobbin receiving mouthk of the receiver will`be either inverted or bein an advantageous position tovfacilitate emptying ofthe bobbins. V* j Y Ordinarily the bobbin receiver must beheld in its normal bobbin receiving "position withmits mouth facing upwardly and it'is Ya. furtherobject of my inventionto provide adetachable connection betweenthereceiver and a support therefor normally'operative to hold the receiver in bobbin eceiving'position but releasable by a lateral shift of-.the receiver so that'the latter can be rotated on the support to bobbin discharging position.

It is desirable to hold the "receiver` in bobbin discharging position by some ymeans which will enableV the attendant to-manipulate the bobbins during the discharging operation without'being required to hold the receiv'er.-'It is accordingly a still further object of my` invention to provide the pivotal mounting for? thereceiver with a secfondary holding means `by which-the receiver can be held with its mouthin position to simplify bob-v Figs. 6 to 9 arediagrammaticviews illustrating the manner in which my invention is operatedA when the loom lis running, and l Fig. 1Y0v indicates the direction i which the loomV is'fat ,restn atqback center. a.

` iouth'of the receiver canv beturned when the lReferring more particularly to Fig. .1,1y have shown a frame I having a lay Il which is reciprocated backwardly and rforwardly byA the.

usual connectors-one of which is indicated at I2. The lay has as huttle box I3 to receive a shuttle S `fromfwhich bobbins are` Vdischarged downwardly during weft replenishing operations;r ,The *descending'loobbins` lgassthrough alslotl I4 inthe lay and areV then guidedlin a downwardlyv and forwardly inclined direction by a bobbin chute' l 5 secured to the layunderthe shuttlebox. ,Y During loom ,operation they bobbin chute 5` traverses an arcuate path as the lay reciprocates and bobbin transfererreplenishment ordinarily occurs when the lay isnear its front center` position.

The matter thus far described is usual in bob bin changing weft replenishing looms and ofA itself ;for1ns' no partjof my present invention. y

^ The expelled'or spent bobbins which descend along the chute are collected in a bobbin receiverv designated generally at R. This receiver has a top bin removal. The receiverds preferably a cloth, bag suspended fromfa metal frame or holder,` but'v the'invention is Vnot limited tos'uch a receiver.;

With thesevand other objects'in view whichwill appear as the descriptionlproceeds.my inventionv resides inthe 'combination andV arrangement of parts hereinafter-described and. set forth. y Y

In the accompanying' drawingfwherein la con-- venient* embodiment of my invention is set forth,

frame4 2,0 defining a bobbin receiving vmouthy M and having front and back bars 2l and 22;'respectively,A and right andr left rearwardly ,and downwardly inclined side bars 23 and24, respectively. Asindicated in Fig. 1 the rear bar 22 is at a lowerlevel than' is the front bar'2l, and is behind `the forward limit ofj thev pathtraversed by the chute; `v

' Thebobbin holding part of the receiver is preferably'a cloth'bag designated at25 ythe upper edges ofwhich-are formed as indicatedlinFig. 5 tofit' around the frame 2l);v The bag hangs by its own weightmore orless inthe form shown in Fig. 1, and the discharged bobbins B collect in the bottom;of .the rbag and require emptying'from Fig'. 1 is a side elevationv of theforwardjpart Y ofV a loom, partly in'section; showing my improved l bobbin receiver in normal positl'ong Fig. 2 is a detailed'plan view'looking' in :the rection of arrow 2, :Figi 1f, v

Fig, 3 is anemarged:front'eievatiozi iookingin: t

the' direction of arrow *3.'Fig.i1. indicating the manner in which-the receivercan bentvedlatg eaux-warfare@ to its support Y In. order jthatthe receivervmay be .manipulated during the bobbinlemptying operation-1 provide the loomk frame I`0fwith a support 30 secured to Atheiralne as at 3l and having a hubor bearing 32" through which the left end ofthefront bar Zlvpas'ses. Bar 2l hasl its left nend bentupwardly to provide an yarm 33 .which cooperates with primaryV and se'condarystops-l and 35, respectively. These stops are xed with respect to the support 30 and may if desired have threaded 'ends 33 tapped into the support as indicated in 32, hence the support 3d provides a sliding and j pivotal mounting for the receiver.v

Under normal conditions arm 33 isU in notch f Y di! and the receiver R will be held in normal position due to the fact that itsweight is, behind the axis oi bearing 32 and arm 33 extends 'upf wardly and is held in notch liti against the primary stop 34.

the frame 23 slightly todisengage armk33 from notch-49, after which he will movey the. receiver laterally tol, the left a sufilcient distance to move o thearm 33 beyond or to the leftv of thestops 34 and 35, thereby disengaging the receiverfrom stop 33. The attendant will then rotate 'frame 2 8 in a clockwise direction fin the direction of arrow a, Fig. 6, the rear bar 22 moving vdownwardly away vfrom the Vpath of chute I5. When the loom is runningit is necessary to swing the frame 2i? in the direction indicated in Fig. 6 due to the fact that the ,rear part of the bobbin rreceiving mouth -M extends behind the path traversed by the bobbin chute and it would not be safe toswing lframe 2li upwardly. l l

Due to the fact `that the bobbin holding part ofthe receiver is a flexible bag thevlatter will take the position indicated in Fig. 6, and as the attendant 'continues toturn frame` 20 in a clock- Wise movement as indicated by arrow b, Fig. '7, the back'bar 3.12v will engage the front Wall 45. Continued movement of the frame 29 will eventually bring vit to the position shown in Fig. 8 with the bag depending from back bar 22 which now is in front of the bar 2l and extendsinto the aisle in front of the loom. The mouth of the receiver fis now'in'verted and faces downwardly.

'.I'he'arm V33 is now -in the dotted line position indicated 'in Fig.'3, and by a slight sliding move# ment ofthe receiver to the right said arm will move in front of the secondary stop 35 and then int'o notch 4l. The frame 2!! is now supported in the inverted position shown in Fig. 8 and the attendant canlift thej bag by means of a tab 48 secured to it to empty .the bobbinsinto a carriage C or the like which is portable and isrmoved from loom to loom. This carriageis in the Yaisle in front of the loom and the inverted mouth of the receiver will be over the carriage when the parts are in the position shown in Fig. 9.

The bag 25 is then allowed yto return to the position shown in Fig. 8, after which the operations described are reversed, that is, arm 33 is detached from notch M and the frame 20 slid laterally to the left asgviewed in Fig. 3 so that arm 33 can swing :upwardly clear of both the secondary'and primary stops, after whicha-slight lateral movement to the right will reestablish the receiver in its normal pesitionlwiththe arm 33 innotch 43. y A

The loperation just described applies whenv the'ioorm is runningjbut if--it is arrest with'. chute I5 in rearward position,l it isobvious that` frame Ztl can be turned'in `a counter-clockwise direction without sliding kbar 21' in vbearing 32'.,

see arrow c, Fig. l0. 'When operated in 'this When it is desired to empty the receiver the attendant will lift the rear end ,oi

Areceiver of a weft replenishing loom, the receiver being rotatable about an axis which as shown herein-r is horizontal and substantially parallelA to the length -of the .lay as seen in Fig. 2 so that the mouth of the receiver can be swung to a forward inverted position to facilitate 4 emptying ofthe bobbins. It Will also be seen Vthat the lmounting 30I provides a sliding and pivotal j-support 4for the receiver, and that slight l,lateral movements of the receiver affect disengagement of it with respect Yto the holding or Lsupporting stops 34 and 35, thereby enabling the frame 20'jto be turned as described. During loom operation the chute traverses a path the forward part of which extends over the rear part o .the receiver mouth M, and under these conditions the frame '2"0 .shouldfbe turned in the directionindicated .by arrows a and b in Figs. Gand 7re'spectively. When the loomris at rest, however, and the chute is 'in rearward non-interfering position the frame 2B can be turned in a counter-clockwise direction.indica-ted in Fig. l0 without sliding the receiver laterally relatively to Imounting 30.

fHavingsthus described my invention it will be seen `that changes and `modifications may be made vtherein by those. skilled in the artwithout departing from the spirit and scopevof the invention and I do not wish to belimited to the details herein disclosed, ibut What'I claim is:k
